William Edward Hickey (September 19, 1927 – June 29, 1997) was an American actor. He is best known for his Academy Award-nominated role as Don Corrado Prizzi in the John Huston film Prizzi's Honor (1985), as well as Uncle Lewis in National Lampoon's Christmas Vacation (1989) and the voice of Dr. Finklestein in Tim Burton's The Nightmare Before Christmas (1993). Hickey had a long, distinguished career in film, television and the stage. He began his career as a child actor on the variety stage and made his Broadway debut as a walk-on in the 1951 production of George Bernard Shaw's Saint Joan, starring Uta Hagen. He performed often during the golden age of television, including appearances on Studio One and Philco Playhouse. His most important contribution to the arts, however, remains his teaching career at the HB Studio in Greenwich Village, founded by Hagen and Herbert Berghof. George Segal, Sandy Dennis, Barbra Streisand, and Sandra McClain all studied under him. He was a staple of Ben Bagley's New York musical revues, he can be heard on several of the recordings, notably Decline and fall of the entire world as seen through the eyes of Cole Porter. Hickey enjoyed a career in film, television and theater. In addition to his work as an actor, he was a respected teacher of the craft. Notable for his unique, gravelly voice and somewhat offbeat appearance, Hickey, in his later years, was often cast in "cantankerous-but-clever old man" roles.
